APPARATUS FOR SUPPLYING STEAM TO CUPS OF TELESCOPIC GAS=HOLDERS.

SPECIFICATION forming part of Letters Patent No. 397,836, dated February 12, 1889.

Application filed November 16, 1888. Serial No. 291,017- (No model.)

To all whom it may concern:

Be it known that I, SAMUEL CUTLER, engineer, a subject of the Queen of Great Britain, residing at Millwall, in the county of Middlesex, England, have invented new and useful Improvements in Apparatus for Supplying Steam to Cups of Telescopic Gas-I-Iolders, of which the following is a specification.

This invention has reference to the construction and application of apparatus whereby the cup or cups of telescopic gas-holders may be supplied with steam, hot water, or other fluid for the melting of ice for the prevention of the water being frozen or for other purposes. Under ordinary circumstances the upper lift or lifts of the gas-holder on rising carry with them the cup or cups filled with water, but on rising above the top of the tank the water is exposed in severe weather to the liability of being frozen or during heavy gales of wind to being blown out and the seal broken, thus allowing a serious escape of gas; and it is with a view to remedy the effect of these conditions that the present invention has been devised.

For the more easy understanding of this invention drawings are attached hereto, Figure 1 being a side elevation of a portion of a telescopic gas-holder and column with the outer lift partly up and with the present in 'vention applied. Fig. 2 shows the position of the various parts when the outer lift is at its full height, and Fig. 3 is an enlarged view of the appliance attached to the grip of the outer lift.

In order that this invention may be carried out, I place at. the edge of the tank a pipe which may encircle or partly encircle the gas-holder. FY01!) this pipe rise one, two, or more vertical pipes, A, which reach to a certain distance above the top of the tank. To the upper end of each of these pipes there attached a strong flexible tube, l3, long enough to reach and enter the cup when at its extreme height. Each flexible tube is supported by passing over a pulley, which is suspended by a cord, chain, or rope that passes end of the cord, chain, or rope being provided with a counterpoise-weight, G, so that on the rising and falling of the gas-holder the slack of the flexible tube is always taken up. Instead of the -flexible tube or tubes themselves entering the cup, the tube or tubes may be connected to a pipe, D, attached to the grip of the outer lift or lifts and partly or entirely encircling the same, and from this pipe any number of short pipes, E, having valves H, may descend and enter the cup. By connecting the pipe at the top of the tank with a supply of steam, hot water, or other fluid the steam. or fluid may be injected into the cup when the holder is at any altitude, and thus prevent the freezing of the water therein, or melt ice that may have been already formed. If the pipe is connected to a water-supply, water also maybe injected into the cup when the gas-holder is at any altitude for the purpose of restoring liquid to the cup, should any portion of the water be lost by leakage, heavy gales, or other causes.

It is obvious that the foregoing apparatus may be adapted to gas-holders having three or more lifts.

yloth to obviate emulensation of steam and chafing of'the flexible tube, almost all the pipes and tubes are covered with. some suit;- able non-heat-conducting material. Cocks, taps, or valves are introduced at suitable points in the course of the pipes or tubes to regulate or out irel y cutoli' the supplyof steam, water, or fluid, as may be desired.

Having now particularly described and as certained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is l. The combination, with the liq uid-eontaining cup of a rising and falling telescopic gasl1oldcr, of a vertical pipe, A, for convey- .ing a heating-fluid, a flexible pipe, 13, connected with the upper end of said pipe and communicating with the cup, and a rising and falling pulley, supporting the flexible tube and taking up the slack thereof as the gas holder rises, substantially as described.
